While the redevelopment of St. Paul’s Lowertown neighborhood has sparked a resurgence of visitors, there’s at least one enduring event that predates all of the new concert venues, gastropubs, and boutique stores: the semiannual Saint Paul Art Crawl. Though the first official crawl took place in 1991, Lowertown had already been primed as an epicenter for artistic expression, thanks to the efforts of the St. Paul Art Collective (SPAC), which had been hosting events in the neighborhood as far back as 1977. Over four decades later, they’re still at the helm. In this season’s crawl alone, some 300 artists are expected to display the idiosyncratic scope of expression revealed in their chosen medium. The estimated 20,000 attendees face a new challenge in navigating a much larger space since the event has expanded beyond its Lowertown origins. Thankfully, the event website, saintpaulartcrawl.org, serves as a valuable repository of information, including a comprehensive guide to the participating artists and a searchable directory for planning a crawl expedition.
